Oct 27 (Reuters) – Harmonic, the AI startup co-founded by Robinhood CEO Vlad Tenev, said on ​Tuesday it was expanding ‌its Aristotle model from mathematical proofs into software and chip design verification, as AI’s growing use in detecting ‌software ​flaws draws increased ⁠scrutiny.

Researchers recently used ⁠the technology to uncover critical bugs in PHP, prompting a global rush to patch the ​vulnerabilities.

Here are more details:

• Backed by Nvidia’s venture capital arm, ⁠Sequoia and Ribbit ⁠Capital, Harmonic raised $120 million ​in a funding round last November ​that valued it at $1.45 billion

• ‌Harmonic is developing what it calls “mathematical superintelligence”, a reasoning-focused AI system aimed at reducing hallucinations ⁠and factual errors

• The company said Aristotle can now verify software written in ⁠C ‌and chip designs written ⁠in Verilog

• US fusion ​lab ‌DIII-D said Aristotle rebuilt ​part of ⁠its reactor-control software in four hours from one research paper and a 254-word prompt
